VIBRATORY MASSAGE APPARATUS.

Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed January 10, 1998. Serial No. 410,219.

To all whom it may concern:

Be it known that I, FRED R. KUNKEL, a citizen of the United States, anda resident of Edgewood Park, in the county ofAllegheny and State ofPennsylvania, have invented a new and useful Improvement in VibratoryMassage Apparatus, of which the following is a specification.

My invention relates to vibratory massage apparatus and it has specialreference to such devices as are operated by rotatable driving shafts.

The object of my invention is to provide a simple and durable device ofthe class above indicated, that shall embody a plurality of applicatorsand means for adjusting the extent of the motions produced therein.

According to lny present invention, I provide a relatively inexpensivedevice having a plurality of applicators to which different motions areimparted from a single driving shaft, the adjustment of certain of themo tions being readily effected while the de-v vice is in operation.

Figure 1 of the accompanying drawings is a side elevation, partially insection, of a device constructed in accordance with my invention, andFig. 2 is a detail plan view of the applicators adjustment of which maybe effected during the operation of the device.

Referring to the drawings, the device here illustrated comprises a shaft1, which may be rotated directly or indirectly by any suitable motor, adisk 2 secured thereto and driven thereby, a supporting frame 3 and aplurality of applicators 4, 5, and 6.

As illustrated in the drawings, a propelling motor 7 constitutes a partof the stationary frame 3, the rotatable member 8 of this motor beingmounted on the shaft 1. This motor may be of any suitable design and maybe adapted to receive its energy from sources of alternating or directcurrent electricity.

The disk 2 is provided with a radial slot 9 in which a bearing block 10is adjustably supported by means of a screw 11 which is rotatablymounted at t-he end of the slot in the edge of the disk. A member 12,the center line of which is substantially parallel to the shaft 1 isrotatably mounted in the bearing block 10 and projects outwardlytherefrom. The applicator 4 is secured to the outer end of the member 12and its eccenr tricity, relative 'to the shaft 1, may be adjusted bymeans of the screw 11. The motion imparted to the applicator 4 isobviously a circular rubbing motion.

A rod 13 extends through a hole 14 in the member 12 near the bearingblock 10 and is supported at one end in a relatively stationary bearingblock 15 which is located near the extremity of a handle 16 by which thedevice may be supported in the hand of the user. The handle 16constitutes a projection from the stationary frame 3 and is providedwith a hole or passage 17 through which the rod 13 extends, this rodbeing substantially perpendicular to the center line of the member 12and being adapted to slide through the hole 14 as a pendulum motion isimparted to it by the member 12 when the latter is in eccentric relationto the shaft 1 and is operated by it.

The stationary bearing 15 is in the form of a clevis, the bodyprojection 18 of which is screw-threaded and is engaged by a nut 19 thatis rotatably mounted on a plate 20 at the outer end of the handle 16. Byturn-- ing the nut 19 in the one direction or the other the position ofthe bearing block 15 may be adjusted, thereby varying the length of thatportion of the rod 13 which is between the bearing 14 and its outerextremity.

As shown in Fig. 2 of the drawings, a pair of short shafts 21 and 22project from the outer extremity of the rod 13 in a plane perpendicularto this rod and at right angles to each other. At the outer extremitiesof the shafts 21 and 22, applicators 5 and 6 are respectively located.The shaft 22 lies sub- 13 which is produced by the eccentric action ofthe member 12 and, consequently, a reciprocating rubbing action isproduced by the applicator 5 while a pounding or picking eect isimparted by the applicator 6.

Since various structural modications may be effected in the deviceillustrated without departing from the scope of my invention, I desirethat only Such limitations shall be imposed as are indicated in theappended claims.

I claim as my invention:

1. In a massage implement, the combination with a driving shaft, aneccentric member disposed parallel thereto and actuated thereby, a rodlaterally disposed with referstantially in the plane of motion of therod- Y 1G l Which one extremity ofthe rod is pivotally ence to saidmember and-operatingthrough ajholetherein, of applicators secured to oneI extremity of the rod and to the outer end of the projection,respectively. 1

thereby, a rod laterally disposed With refer# 2. In amassage implement,the combina;-

tion With a driving shaft, an eccentric member disposed parallel theretoandv actuated ence to said membervand operating` through aliole therein,and an adjustable bearing to secured, of meansfor adjusting the degree Yof eccentricity of the eccentric member, and

applicators secured to the extremities of the rod and said member,respectively. Y

' 3. In amassage implement, the combination With a driving shaft, a disksecured to one endof the shaft and having a radial slot, an eccentricmember attached to one end vof the driving shaft, means for adjustingthe degree of eccentricity of said member, a

' stationary frame having'a handle the center line of which issubstantially perpendiculary lto the center line of the driving shaft,and

an applicator' secured lto the outer end ofthe y eccentric member, of arod'substantially perpendicular to the eccentric member and operatingthrough ahole therein andan ad` justableA bearing near the extremityofthe handle, one end of said rod being pivotally vsecured to theadjustable bearing, aiidapplicators projecting laterally from the. otherendofthero. I

LIn a massage implement, the combina-v tion With a stationary frame, ashaft rotatablyfmounted thereon,'a driving motor there.

for and a disk secured toV one extremity of `the shaft ande having aradial slot, of a block adjustably mounted in the radial slot, aneccentricmember 'rotatably supported by the adjustable block in alinesubstantially parallel to the driving shaft, a rod perpendicular to theeccentric member and operating through a hole therein, a bearing towhich one end of therod `is pivotally se-` cured` and applicatorsprojecting laterallyY from the other end of the rod.

v5. In a massage implement, the combina` ber, anf'adjustable supportvfor one end of said rod andan applicator on the other end thereof. Y ry y A 7. Ina massage implement, the combination With a drivingshaft anda laterally ad- V j ustable member attached to one end thereof, of alaterally disposed rod having an inter-l mediate loose connection toysaid adjustable member andan applicatorat one end, and an adjustablesupport upon which the other lend of the rod is vfpivotally mounted. 'Y

8. YIn massage implement, the combination With a driving shaft anda'laterally adjustable member lattached to Lone end thereof,

lof a laterally disposed rod having an intermediate loose connectionV tosaid adjustable member and an applicator at one end, and a support uponwhich theother end of the rod is pivotally mounted.v y
